Introduction Geotechnical widely exist in nature, and as a structural engineering application is the most common and most massive materials, because of its porous, heterogeneous and structural property,and under the action of load of its internal structure and mechanical properties of continuous change, make it become the constitutive relationship of geotechnical engineering circles problem.The constitutive model of rock and soil research has two major branches: one is the mechanics of continuous media, through its continuous medium mechanics phenomenological method and dissipative process of irreversible thermodynamics, materials on the macroscopic mechanical response, the material constitutive model;Another kind is the micromechanics, it through the soil microstructure and micro crack (void ) damage evolution process, study material deformation and damage the relationship between variables, derivation of the constitutive relation of material.Although both methods are different, but
The use hypothesis of Sidoroff[4] elastic energy equivalence,role of stress in the damaged material and nondestructive material complementary elastic energy is in the same form .For nondestructive geotechnical materials complementary elastic energy can be expressed as: (3) and for damage of geotechnical materials complementary elastic energy can be expressed as (4) (5) where is the flexibility matrix, the damage effective flexibility matrix, the elastic stiffness matrix, and the stiffness matrix for injury.
It can get the anisotropic damage constitutive relation of geotechnical materials for: (6) Considered ( soil layered transversely isotropic ) material, then reduced to transversely isotropic damage soil damage variable matrix [5], D1 = D2 = DH, D3 = DV.
